Re: MIG Welding Aluminum?

Mig welding aluminum with a spool gun, or push pull gun has really come a long ways. If a guy was going to do a lot of it a machine with run in heat would be very nice. Other wise you have to adjust your travel speed accordingly, go slow at the start, and faster at the end of the weld. For thin aluminum a machine with pulse is also very nice. I have a Lincoln Invertec V350-Pro with pulse, and the SG spool gun. One thing I like about that spool gun is the notched contact tips. When you get burn back these tips seem to survive longer. With the pulse I have welded 16-GA with no problems. And up to 3/8-inch aluminum.

Well I'll get right on that. At around $5.00 a pound for aluminum wire I'll do some testing so you can save a few cents on contact tips. [URL=http://imageshack.us/photo/my-images/149/hehegl.gif/][/URL]
